Estudo retrospectivo de biópsias de pele : um comparativo da dermatite atópica canina com as demais dermatoses

Abstract

Canine atopic dermatitis (CAD) is a genetic trait of the disease, promotes the loss of the epidermal barrier functioning and allergic sensitization to environmental allergens. Dogs of various breeds and with an average age of one and three years are predisposed. The diagnosis takes time, because the CAD should be excluded from pruritic diseases, therefore this study aimed to make a retrospective study of cases of dogs submitted to skin biopsies, and associate clinical and laboratory findings of the cases of CAD with other non-neoplastic dermatoses. Fifty-two biopsies were performed, and 11 dogs with CAD, 14 (26.92%) without CAD and 27 (51.92%) with neoplastic diseases. Pruritus was observed in all atopic dogs and the age of onset of signs was 4.4 years. The ringworm and infection by Staphylococcus sp. and/or Malassezia sp. were the most common diseases in cases of CAD. The biopsy is another diagnostic tool, which added to the clinical and epidemiological findings assists in confirming the DAC, improving the quality of life of atopic dogs and their owners.
